Device for holding a touch-sensitive surface

Abstract

A device for holding a touch-sensitive surface in a frame comprises deformable means arranged between the upper rim of the frame and the upper face of the surface, and capacitive means arranged between the lower rim of the frame and the opposite face of the surface to detect a displacement of the surface. The deformable means and the capacitive means are arranged on the perimeter of the frame so as to hold the surface in the frame.

1 . A device for holding a surface of large size to be touch-sensitized comprising:
 a monolithic frame, having an upper rim and a lower rim, for embedding the surface of large size to be touch-sensitized, the surface having an upper face and an opposite face;   deformable means arranged between the upper rim of the frame and the upper face of the surface; and   capacitive means arranged between the lower rim of the frame and the opposite face of the surface making it possible to detect a displacement of said surface;   wherein the deformable means and the capacitive means are arranged on the perimeter of the monolithic frame so as to hold the surface in said frame.   
     
     
         2 . The device as claimed in  claim 1 , wherein the deformable means are arranged facing the capacitive means. 
     
     
         3 . The device as claimed in  claim 1 , wherein the deformable means are arranged partially overlapping the capacitive means. 
     
     
         4 . The device as claimed in  claim 1 , wherein the deformable means are of rigid or semi-rigid material. 
     
     
         5 . The device as claimed in  claim 1 , wherein the deformable means are capacitive sensors. 
     
     
         6 . The device as claimed in  claim 5 , wherein the capacitive sensors are coupled to the capacitive means arranged between the lower rim of the frame and the opposite face of the surface to cooperate in the detection of an interaction on the surface. 
     
     
         7 . The device as claimed in  claim 6 , wherein a capacitive sensor comprises a first electrode secured to the surface and a second electrode separated from the first by a dielectric and secured to the frame. 
     
     
         8 . The device as claimed in  claim 1 , comprising at least one seal which extends between the surface and the lower rim of the frame. 
     
     
         9 . The device as claimed in  claim 1 , wherein the surface is a vehicle dome light. 
     
     
         10 . The device as claimed in  claim 1 , wherein there are least three of the deformable means and there are at least three of the capacitive means.
